Solaris S

The Solaris S range is a virtually endless range of transparent clear or coloured optical filters used in a variety of applications for contrast enhancement, colour conversion or colour correction in displays using for example VFD, LCD or LED technology.

Properties of Solaris S

Solaris S optical filters are used to control or manipulate the light emitting from a display. This is done by adapting the filter’s transmittance to the wavelength of the light emitted from the display.

An important distinction is made between broad-band and selective filters. Broad-band filters are basically gray-shaded filters which allow for the transmittance of all light (colours). They are therefore often used in applications in which contrast enhancement is required without loss of the full colour spectrum. Selective filters are designed to only transmit specific wavelengths of the light, i.e. specific colours. Selective filters are especially suitable for applications requiring colour correction and contrast enhancement of monochrome displays. Click to see examples.

You can create a high degree of contrast by choosing either a filter with a narrow transmittance curve or a dark, grayish tinted filter. The latter will make information from the display stand out clearly against a dark, almost black, background. This may increase readability and, at the same time, provides an elegant design function, some times referred to as “black panel design”.

PSC offers an extensive range of ColourMatching services. Using proprietary computer-based C&L® simulation software, PSC can calculate and create coloured filters and Colour Conversion Filters meeting almost any customer specified colour or chromacity target.

PSC has a selection of more than 20 different coloured Solaris™ S optical filters especially suited for Vacuum Fluorescent Displays (VFDs). Contact us for more information. 

Further refinement

Solaris S optical filters can be supplied with for example a Fine Mat surface treatment, which prevents distracting reflections from the surroundings without reducing the quality of the signal. The filters can be produced as EMC filters which have an embedded metal mesh for the attenuation of electromagnetic noise. It is possible to have the filters machined, for instance, using laser cutting and milling techniques. The filters can also be supplied with silk screen printing.
